Abstract:
The asymmetric unit of the title compound, [PtCl2(C5H11NO2S)], a D-methionine derivative, contains two molecules with opposite chirality at the S atoms. The amino acid acts as a bidentate ligand and coordinates simultaneously through the N (amino) and S (thioether) atoms. The molecules are packed in pairs which are connected through two hydrogen bonds between the protonated carboxyl groups, with O.O distances of 2.633 (10) and 2.663 (12) A.
